The universe is endlessly vast. A single atom is impossibly small. And somewhere between those two extremes lies everything that has ever existed.
We believe that feeling — the electric, spine-tingling sense of scale — belongs to everyone. Not just scientists. Not just students. Everyone.
That's why we built Universal Zoom.
WHAT YOU CAN DO
• Zoom seamlessly from the Planck length to the edge of the observable universe — about 300 objects presented to perfect scale.
• Compare any two objects side by side: how many Earths fit inside Jupiter? How does a virus measure up against a skyscraper? Instant, visual, intuitive. (No other scale app lets you do this.)
• Go deeper with audio narration and short, accessible explanations — the facts that matter, in plain language.
WHAT YOU'LL EXPLORE
• Elementary particles — quarks, leptons, and bosons. Atomic nuclei, atoms, and DNA. Living cells. Animals and landmarks. Planets, stars, and galaxies. A deep dive into physics, biology, and astronomy — with short, plain-language articles that make even particle physics easy to grasp — in 40 languages, with metric, imperial, or powers-of-ten units.
• Real high-resolution photos and electron microscope images, where possible. Original artwork for things that can't be photographed — like elementary particles and DNA structures.
• No ads. No in-app purchases. Pure discovery.
BUILT WITH YOU
We're a team of two (Andrey and Oksana) from Canada who have poured a decade into this app because we genuinely love science. Most objects come from community suggestions — carefully fact-checked and updated with every new discovery. Over 200 more are already in the queue.
FOR EDUCATORS
Used by teachers worldwide to visualize scale, build measurement intuition, and turn abstract numbers into "aha" moments. Available at 50% off for schools via Apple School Manager (20+ copies).

So you think you are the centre of the Universe? Think again.I love wandering through the timescale in this app it is awe inspiring to realise how many things go right everyday! Highly educational and used well, very thought provoking. It’s the sort of program that should come free on every device - might lead to a kinder world. iPad experience exceptional and animations very smooth.
Amazing!

This app is amazing and fascinating and interesting and brilliant! I don’t know what else to say. Every update shows more amazing objects and how they fit in our world. The visuals are wonderfully done and the info on each object is simple enough for anyone to understand. It’s fun and educational but not at all limited to school aged children. Adults will enjoy this app just as much.

Thank you for such an amazing review! It means a lot to us. 😊
An amazing app

I am a space nerd and it gives you some real understanding of the vastness of space it even has the Death Star from Star Wars, my only criticism is that it does not have Starkiller Base as well. It also goes the other way from the vastness of space to even smaller than sub atomic particles! Truly amazing and very smooth with the transition, you can even compare objects.
Fantastic app

Brilliantly put together. Really smooth and 100% no bugs. Super fun to use and teaches you so much about our place and SIZE!It leaves you in awe thinking of how big yet how small you really are! Great for kids but great for anyone interested in science. From the largest sun and foreseeable galaxy to the smallest measurable unit and smallest snowman!! I highly recommend this app!!

Thank you for such a great review!
Version 3.0 is our biggest expansion of the Physics part of the app yet.
• A whole new kind of object — point particles like quarks, leptons and bosons. Having no measurable size, they stay put as you zoom instead of growing or shrinking.
• 39 objects added or significantly improved — point particles, plus more atomic nuclei and atoms, and a handful of larger objects too.
• Particle physics is a tricky topic, so we added 5 short articles that explain it in a simple, easy-to-follow way — with many more articles to come.
• We improved the information for many objects, refreshed the images for several of them, and polished translations and voice-over pronunciation.
• We fine-tuned the soundtrack volume based on your feedback.
Thank you for your continued feedback — it truly helps make Universal Zoom better with every update!
